Overview:
This thread is a guide on how to fix the apply_patch_check error message experienced during an upgrade of the Android OS. Specifically, this will detail the steps for an upgrade of Jelly Bean from 4.1.1 to 4.1.2 on the Nexus 7 with CWM Recovery for a user of Windows. I'm sure similar steps will work for other recoveries/upgrades/devices and PC OSes.
You should only bother with this if you don't want to flash the entire system.img file to your phone, which is way easier.
Here is an example of the error message I'm talking about:
Code:
assert failed: apply_patch_check("/system/app/Chrome.apk", "819b34b66335c6faec86404d736a002b8871600", "9d6b55e63b0bf20bea433fb1ee7089f88ab73fb6")
E: Error in /sdcard/03a4eaf95f73.signed-nakasi-JZO54K-from-JRO03D.03a4eaf9.zip
(Status 7)
Installation aborted.
A few notes about the error:
This doesn't have to happen with the Chrome.apk specifically -- it could happen with any app in /system/app or .so in /system/lib.
Those random strings of numbers/letters are SHA-1 hashes of the apk.
The first one is the hash of the apk installed on your device. In my example, this happens to be the version of Chrome that comes with JB 4.1.2.
The second one is the expected hash of the apk that comes with JB 4.1.1.
Cause of the problem:
The reason this error occurs is because the file was somehow modified from its original state. In my case -- and most likely your case -- this was done by Titanium Backup. TB has an option to "Integrate updates of system apps into ROM", which will cause the apk in /system/app (and associated library files in /system/lib, if needed) to be overwritten with the updated apk.
Solution:
Download this zip file which contains the full /system/app and /system/lib directory from the JB 4.1.1 factory image. *
Extract the zip to a location of your choosing on your PC.
In the extracted folder, locate the .apk or .so file referenced in the error message on your device.
Copy this file to your device via your preferred method (USB cable works fine). I put my file in /sdcard/Download.
On your device, use a root file explorer to move the file from /sdcard/Download to /system/app (or /system/lib).
If you don't have a program that can do this, I use ES File Explorer. Be sure to go to Settings > Root Settings and turn on Root Explorer, Up to Root, and Mount File System.
Reboot into your Recovery and try to install the update again.
Repeat steps 3-6 for each subsequent file that produces an error. You will basically need to do this for each app you integrated using TB and maybe a few library files, too. **
* Future updates (above 4.1.2):
Since I won't be keeping the zip file from step #1 up-to-date, here's how to get the directories that I included in the zip for yourself:
Obtain a factory image for your device's current Android version (the version you're updating from).
For JB 4.1.1, this file is called nakasi-jro03d-factory-e102ba72.tgz.
If you're reading this guide at a later date, the JB 4.1.2 file is called nakasi-jzo54k-factory-973f190e.tgz.
You can try your luck at the official Google site, but they seem to only provide the version you're trying to update to, not from.
Extract the .tgz file somewhere on your PC.
Locate the image-naksi-jro03d.zip file and extract that, as well.
In the folder you just extracted from the previous step, located the system.img file.
Download and use a program called sgs2toext4 (View attachment 645320) to convert the system.img to system.ext4.img. ***
Download and use a program called Linux Reader to open system.ext4.img.
Do this by going to Drives > Mount Image > Next > select your file.
It will then be listed under the Hard Disk Drives section in red as "Linux Ext Volume 1".
Navigate to: Linux Ext Volume 1/system.
Right-click on the app (or lib) directory and pick Save > Next > Output to dir of your choice.
You now have the directories that were included with the zip file from Solution step #1, so just follow those steps now.
** How to avoid repeating steps:
If you'd rather not have to try to reinstall after updating only one file, just to find another file that needs updating, try this:
Obtain the /system/app and /system/lib folders from the factory image and save them to your PC.
For the sake of this guide, let's say you save them to C:\factory_app and C:\factory_lib.
Copy the /system/app and /system/lib directories from your phone to your PC.
For the sake of this guide, let's say you saved them to C:\phone_app and C:\phone_lib.
Download the File Checksum Integrity Verifier utility from Microsoft.
Start > Run > cmd
fciv.exe -sha1 -xml factory_app.xml -wp C:\factory_app
fciv.exe -sha1 -xml factory_app.xml -v -bp C:\phone_app
Don't ask me why, but you need to use -bp instead of -wp for the second command.
Don't forget the -v on the second command.
The output of the last command will show you the list of files that are different. These are the files you need to take from C:\factory_app and put into the /system/app directory on your phone.
Do the same for the lib directories (just replace all instances of "_app" with "_lib" in the previous commands).
Summary:
I hope that this post helped some of you who really didn't want to have to flash the system.img or wipe your device just to update. In the future, use TB to back up the original.
I wouldn't normally bother writing up a guide like this (it took almost as long to write as it did to figure out how to do this) but I couldn't find this solution anywhere even though I saw that I wasn't the only person with the problem. Sorry for not posting this guide sooner (update has been out for a while now), but the forum required me to make a bunch of useless spam posts before I could include any links in my guide and I didn't get around to making those posts right away.
*** I would like to thank balamu96m for his guide on extracting data from the system.img file and drphrozen for making the sgs2toext4 program.
Thanks for this. Will try now.
Worked great. Had to copy the apk and odex file.
Good job! It's great to see the steps for Windows users!
Just a heads up that I simply extracted the files I needed from and on my N7 using Root Explorer, without using my PC at all.
Great guide! Method worked perfectly on my Nexus 7 going from 4.1.2 to 4.2, thanks
Please... is there some other way to update the files w/o installing Java on my Windoze PeeCee? I accidentally messed up my YouTube.apk with Titanium Backup... now I can't update from 4.1.2 --> 4.2 JB.
EDIT: JavaPortable FTW... updating (fingers crossed)
EDIT: SUCCESS TY OP!
For anyone who flashed the 4.2 clock/keyboard already
Hey, for anyone who flashed the 4.2 clock and keyboard on their Nexus 7 already and need to roll back to do the 4.2 update, I used OP's method to make a flashable zip that puts the 4.1.2 clock and keyboard back.
Worked perfectly for my Nexus 7 to get me up and running. Hope it helps anyone!

Hi can you post a guide for galaxy nexus? Or if it is the same, can you post the link of JB factory image for galaxy nexus? Sorry, I can't find any thread for galaxy nexus, and I don't want to complete flash the stock image since I don't want to wipe my phone.
Thanks in advance!
Nice Guide
perfect, the guide works just fine. Now finally running 4.2.
Awesome guide... Thanks... Happily running 4.2 now aften beeing stuck at libutils.so...

I don't have a Galazy Nexus, but I think the steps should be the same. Here is a link to the factory images: https://developers.google.com/android/nexus/images#takju . It looks like they now have links for older versions, rather than just the newest images (which is how it was when I made my guide). So that's pretty sweet.
Thanks a lot man, i succeeded to "patch" my system files to update from 4.2 to 4.2.1. I first check what files didn't correspond with fciv (9 files counting both apks and odex) and then replaced them in system/app. In fact they were the apps I previously integrated with tb (learned lesson: never do it if you want to remain stock and receive OTAs). I also noticed many not-matching files in system/lib but i didn't touch them and the update went smooth the same.
Another thing: when in the OP you say it's way easier just to reflash the system.img you mean just run from bootloader "fastboot flash system system.img" (taken from the factory image as usual) or there's some other thing to do in order to fix the system partition in the right way?

Yes. I am having the same issue. I cannot update mine from 4.2 to 4.2.1. I wonder to know which original stock image you have used. Can you list a detail procedure?
Thank you very much.

Yes, that's what I mean. The reason I didn't want to do this on my device is because I had modified some other system files that I wanted to keep the modifications for.
Wow, thanks a lot OP! Your guide helped me fixing an error during the update to 4.2.2 on my Nexus 4.
please include a video ,im getting lost in the details
solved.
Android Boot Manager (ABM), my goal is to make the procedure (Backup, Unpack, Edit, Repack and Flashe boot.img or recovery.img) so easy and accessible to all users without resorting to the command prompt , only a single click to get a quick and successful outcome at the same time .
This is the third version of the program.
Source (GITHUB SOURCE https://github.com/aToxyD/android_boot_image_manager_apk).
WHAT'S NEW
- Some optimization.
- Add new Text Editor with high syntax.
THANKS
* xiaolu, original author of boot.img tool(GITHUB SOURCE https://github.com/xiaolu/mkbootimg_tools).
* Modding.MyMind, for his heavily modification of boot.img tool.
* Tah Wei Hoon, for TextWarrior.
* Dmytro Tarianyk, for Android Floating Action Button.
* Anthony Restaino, for Grant.
IMPORTANT
- Root is only necessary for Unpacking boot patched by "superSu or Magisk" and Backup/Flash Operations, so if you want to unpack stock boot or you have your favorite flasher apk like "Rachr", if so you dont need to check "Root Access" in settings menu.
- Please uninstall any previous version of ABM before installing the newer.
I do not like people to coming here and take what they wanted and leave like a thief , at least leave a comment. . .
This work is for all, so help your self.

This is the second version of the program.
WHAT'S NEW
- Corrected some bugs related to compatibility with Android 6.
- Use xiaolu mkbootimg tools (GITHUB SOURCE https://github.com/xiaolu/mkbootimg_tools)
TODO
- add support to x86, mips arch.
- add support to put files to unpacked folder.
- add support to combinedboot , in Xperia device recovery ramdisk is combined with system ramdisk.
IMPORTANT
- The apk need root access to work.
- Note that make change by adding files to unpacked folder with root explorer, the owner will be root and the apk will not work, if you do this you must change the owner to ABM apk.
THANKS

The things I reverted are:
Changes made by adblock
Magisk mods: emojiOne and Mi A2 Camera app (I thought it was an enhanced version)
I flashed the original boot.img
But after these steps the installation doesn't work.
Other root apps I use:
Greenify, but not for system apps
Uptodown, but it has root privileges denied always
SD Maid. I think I didn't delete anything but maybe I compacted some databases
Any ideas? Is there any way to get more detailed info about the installation error?

Before trying this, I suggest you to backup your files.
Verify the system version in Settings > System > About the device > Version number and download the same version installed in your device:
V9.6.10.0.ODIMIFE
V9.6.13.0.ODIMIFE
V9.6.13.0.ODIMIFE
V9.6.14.0.ODIMIFE
V9.6.15.0.ODIMIFE
Unzip the package (7zip works perfectly to this job) and copy the files boot.img and system.img
1) Copy system.img and boot.img into adb folder
2) go to "settings > system > developer ... > USB deployment and enable it
3) plug you device on your computer, turn it off and turn it on again while holding power + volume down until your screen shows the Xiaomi bunny and "Fastboot".
4) in Fastboot, type "fastboot devices" and make sure your device is listed.
5) in Fastboot, type "fastboot flash system system.img" (without quotes) and wait it finishes.
6) in Fastboot, type "fastboot flash boot_b boot.img" (without quotes) and wait it finishes.
7) in Fastboot, type "fastboot flash boot_a boot.img" (without quotes) and wait it finishes.
8) in Fastboot, type "fastboot reboot" and unplug your device.
This works for me, maybe works for you.

After yesterday an update was delivered, I am now offered a new update. The installation is now running. I noticed after yesterday's update that there were significant "memory / processing delays", which had previously not occurred on my device. The update is 203 mb, yesterday only 103.5mb were delivered.
Hi everyone. I'm scratching my head here and struggling to find a solution that doesn't require root.
I've got a hosts file that I love as it blocks nearly all advert servers on my phone.
I know there are several adblocking apps but they all require root.
I have had to remove root as I have some critical apps that still don;t work, even after hiding magisk from the apps within the Magisk Manager.
I've got a magisk patched image that I can "fastboot boot" with and can edit the hosts file (after remounting /system as rw) but when I then reboot afterwards, the hosts file has been overwritten.
Can anyone help me please or give me a pointer of how to make the hosts edits remain following a reboot?

I am using stock ROM with latest August patches on my Mi A1
You can't without root even if you do it your system partition will be modified and it will result in phone not booting or just safetynet won't pass.
Use a vpn or I'm pretty sure there's app that can fake a vpn with a ad ban list

Interesting idea regarding spoof VPN.
Do you know how the hosts file is generated? If it's copied over from somewhere during boot then could I edit the source file it's copied from?
If it's generated procedurally, might I be able to script it to add my edits during creation?

System partition ? so that's a good idea but you'll have to compile a rom to change this file. On Linux distro the host file is a thing you can modify easily. On android it's just deprecated by google as it's use mostly used as an adfilter. And google is an ad company. That's my guess.
Anyway host file will always need root even on Linux.
Simply because it can be used against you.
The problem is more on apps that blocks you because you're rooted than being rooted for changing this file.
If any app could modify host then bang you go to YouTube and it redirect you to something else.
Maybe for you it's just an adblock file but it's a little more than that.
So sorry but it's root or vpn.

So? Could I possibly extract the system.img from the stock ROM, make the edits there and then recompile?
(I've got a copy of payload.bin that I extracted a few weeks ago, when trying to flash the August security patches (this was before I did a compete flash of stock ROM using fastboot)
That actually seems like it wouldn't take too much effort

This will lead to a corrupt system partition modified. As i said the worse thing is you could not boot and the good just won't pass safetynet.

Ok I understand.
How does the device 'know' that the system partition is corrupt? Does it perform a hash check perhaps?
How would compiling my own custom ROM avoid this same problem?

It does many thing to know that its have been touched. You'll have to modify some stuff and it will work. You'll loose certification but you'll have you own rom.

Any chance you can outline the other stuff I'd need to change?
If it's really in-depth then don't worry but if it's just a few bullet-points that I can Google more info on, I'd appreciate it.

Search "dm-verity" and "safetynet". The first one is what will look at any r/o partition like system and kernel. It's been a long time since i dig into this. I'm not into this anymore.
But You can disable it but you'll loose safetynet, encrypted partition etc... (i may be wrong but you got the idea). And safetynet look if partition have been modified and you are a certified device if it won't pass the banking app and apps like Pokemon go etc won't work.
Magisk hide the fact that the kernel img have been touch and most app that detect it detect just the app itself. That means magisk capability (su, hide and module)
So you could maybe compile stock rom with a custom host file. Never touch vendor partition! Make a backup before! By booting and not flashing twrp. Do not flash twrp just use the "fastboot boot command"
You'll need to make a custom kernel and system img to flash in order to do it.
I'll try to do a rom without anything modded except kernel without dm verity and system with your host and i guess it needs change too.
I dunno if it will pass safetynet after.
Just don't brick your phone ?
Keep in mind that you'll loose ota. There's a chance that the rom work with just some changes but i can be a mess to do.
Why not trying a custom rom like lineage os?
Using their supersu zip won't you be able to replace the host file then remove root?
Once you make a backup a move it to a pc as a savestate. You are free to try different solution

Thanks for info I'll investigate later in the week when I have more time. Monday has arrived too quickly!
Appreciated though
Hi,
Just upgraded my OP5 to Android 10 official stable version. Rooted successfully with Magisk 20.4
Now I'm trying to do some changes to the system folder but they revert back when I reboot.
1- Trying to replace the emoji with another ttf file, as I always did in Pie but the file gets reverted upon restart.
2- Trying to apply hosts file for ad blocking, same issue the file gets reverted as soon as I restart.
it looks like my system partition is reverting itself for some reason, does anyone know why this happens and how to make the changes stick?
PS: I don't want to enable (Systemless hosts in Magisk) because I'm planning to unroot after doing these changes.
thanks..

Just forget to change hosts file manualy, use the better Adbloacker Rootless, Blokada

Hi Mate,
Ensure to give proper permissions as follows: rw-r--r-- (0644) to the file. If it is a folder, the permissions are: rwxr-xr-x (0755)

You can't mount the system partition as rw directly in Android 10. Here's a thread by topjohnwu (slightly technical, but give it a read) on why: https://twitter.com/topjohnwu/status/1259039809361739776
